"This decision is extraordinary and extremely dangerous given the body of evidence that links pay and safety on our roads," Mr O'Connor said.

"The Turnbull Liberal Government has gone from seeking to delay the decision by legislation to now recklessly trying to kill off the tribunal, simply because Malcolm Turnbull doesn't like its decision.

"Labor doesn't want to see people dying on our roads and the facts are that when truck drivers are overworked, safety for all road users is jeopardised."

Mr Turnbull pointed to two independent reviews of the RSRT that called for the body to be disbanded.

A PriceWaterhouseCoopers review found abolishing the tribunal would "result in significant net benefit to the economy and community at large".

The Federal Court last week overturned a stay on the tribunal's ruling.
